Access time

Updated: 10/02/2017 by Computer Hope

The total time it takes the computer to read data from a storage device such as computer memory, hard drive, CD-ROM or other mechanism. Computer access time is commonly measured in nanoseconds or milliseconds and the lower the access the time the better. For example, when reading 100 MB of data an access time of 10ns is a lot faster than 50ns.
